Codeigniter在simplelogin庫中添加字段

Question

我是CI中的新學習者，並且在我的項目中遵循此CI簡單登錄庫(see here)，除了如果我想在數據庫中添加更多字段，一切工作都很好，表，我如何創建和獲取新添加的字段？

這個圖書館的出處只有'id'，'username'，'email'和'password'字段，如果我想添加諸如'address'這樣的字段，並且使它在創建用戶時可用$this->simplelogin->create('user', 'user@mail.com', 'password', 'address', true);並取$this->simplelogin->get_data_user('address');？

謝謝。

Answer 1

您可以更改：

• 添加屬性

  private $ address_field ='address';在數據庫//地址

//確保在你的數據庫必須有場address

長葛函數來創建（）：

function create($user = '', $email = '', $password = '', $address = '', $auto_login = TRUE) 
{ 
     // Check data is set 
     if ($user == '' || $password == '' || $email == '') 
      return FALSE; 

     // Email or User already exists | Probably will not need to check the `address` 
     $this->CI->db->where($this->user_field, $user); 
     $this->CI->db->or_where($this->email_field, $email); 
     $query = $this->CI->db->get($this->user_table); 
     if ($query->num_rows() > 0) 
      return FALSE; 

     // Create user into the database 
     $data = array($this->user_field=>$user, $this->email_field=>$email, $this->password_field=>crypt($password, $this->salt), $this->address_field=>$address); 
     if (!$this->CI->db->insert($this->user_table, $data)) 
      return FALSE; 

     // Automatically login to created account 
     if ($auto_login) {   
      $this->CI->session->sess_destroy(); 
      $this->CI->session->sess_create(); 
      $this->CI->session->set_userdata(array('username'=>$user, 'email'=>$email,'address'=>$address)); 
     } 

     return TRUE; // Created! 
    } 

長葛功能get_data_user（）：

function get_data_user($param = 'username') { // default is get session username 
     $sess = $this->CI->session->userdata($param); 
     if (!$sess) 
      return ''; 

     return $sess; 
    } 

更改登錄功能中的第106行：

$this->CI->session->set_userdata(array('username'=>$row[$this->user_field], 'email'=>$row[$this->email_field],'address'=>$row[$this->address_field])); // Set session data

恐怕沒有簡單的方法來做到這一點

您需要修改庫Simplelogin.php以類似的東西 記裸您需要的地址字段添加到表
